Application filed November 10, 1917. Serial No. 201,275.

To all whom it may concern:

Be it known that we, THOMAS C. JOHNSON and FRANK F. BURTON, citizens ofthe United States, residing, respectively, at New Haven and East Haven,in the county of New Haven and State of Connecticut, have invented a newand useful Improvement in Devices for Loading Box-Magazines; and

we do hereby declare the following, when taken in connection with theaccompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, in

Figure 1 a view in front elevation of our improved devicerfor loadingbox-magazines.

Fig. 2 a view thereof in side elevation with the body part of a papercarton filled with cartridges shown as held in the hand preparatory tofeeding a column of cartridges from it directly into the device.

Our invention relates to an improved device for loading cartridges intoboX-1nagazines for subsequent introduction, as loaded magazines, intomachine guns or shoulder arms, the object being to provide a simple,durable, reliable and rapidly operated portable device of the characterdescribed, the said device being particularly adapted to loadingtapering cartridges directly from paper cartons, though not so limited,since it is also available for loading cartridges fed by hand into thedevice.

..With these ends in view, our invention consists in a cartridgedoadingdevice having a frame provided with a cartridgeguideway, acartridge-loading instrumentalityco-acting with the said guideway, andbox-magazine positioning and supporting means located. at the deliveryend of the said guideway.-

Our invention further consists in a cartridge-loading device having apivotal loading instrumentality, and certain other details ofconstruction and combinations of parts as will be hereinafter describedand pointed out in the claims.

In carrying out our invention, as herein shown, we employ a leaf-likepivotal car tridge-loading instrumentality or head 5 having at its lowerend a straight loadingface 6, substantially as long as the body-portionof a tapering cartridge 7; At its upper endv the said head is providedwith a handle 8 located substantially above an operatingpin 9 extendingtransversely through the lower portion of the head so as to pro ect onreciprocation in the chamber 14 of a tubular upright 15 the lower end ofwhich is secured to a base-plate or pedestal 16 by screws 17 only one ofwhich is shown, the

upper end of the upright being closed by a cap 18 secured to it byscrews 19, only one of which is shown. The front of the upright isformed with a flattened face 20centrally intersected by a vertical slot21 enough.

wider than the head 5 to permit the same, and the arm 10 thereof, tomove up and down in it, the plunger 12 being held against rotation, andthe head against lateral displacement, by the engagement of the sides ofthe arm 10 with the walls of the said slot. Two parallel flange-likecartridge-guides 22 ap lied to the u right, have corresponding inc inedouter e ges 28 for coaction with the respective ends of theoperating-pin 9, the sai guides being furnished with fastening-flanges2e receiving screws 25 by which the guides are secured in place on theopposite sides of the lower end of the slot 11.

clination. The cartridges occupy these in-' clined positions becausetheir body portions are slightly tapering rather than cylindrical. V

Forthis reason they are loaded in the manner described to prevent themfrom cooking or tilting as they enter the magazine. On releasing thedownward pressure upon the handle 8, the plunger spring 40 assertsitself tolift the loading-head 5 to the top of the upright 15 as shownin Fig. 1, for loading another box-magazine. The remaining column ofcartridges in the carton will now be loaded in the same manner into thesame magazine, or into another magazine, as the case may be, supposingeach carton to have two columns of cartridges, which is the usualpractice.

W e claim 1. In a device for loading box-magazines for firearms, thecombination with a frame having a cartridge-guideway, of acartridgeloading instrumentality adapted to traverse the saidguidewayand arranged so that the inclination of its loading-face will beprogressively changed to compensate for the gradual changing of theinclination of the column of cartridges in the guideway, due to thetaper of the cartridges, and means for positioning and supporting abox-magazine at the cartridge delivery end of the said guideway.

2. In a device for loading box-magazines for firearms, the combinationwith a pivotal cartridge-loading instrumentality, of means forprogressively swinging the said instrumentality during the loading ofthe cartridges into a box-magazine, whereby their change in inclinationor pitch due to their taper, is compensated for.

3. In a device for loading box-magazines for firearms, the combinationwith means for positioning and supporting a box-magazine, ofcartridge-guides located above the said means, a pivotalcartridge-loading head coacting with the said guides and having aloading-face, and means for swinging the said head upon its pivot so asto progressively change the inclination of its loadingface to insure theintroduction of the successive cartridges into the mouth of theboxmagazine at the same angle.

4. In a device for loading tapering cartridges into box-magazines forfirearms, the combination witha pivotal loadinghead, of means forprogressively swinging the said head during the loading of the car-'tridges into a box-magazine, whereby their change in inclination orpitch due to their taper, is compensated for.

5. In adevice for loading cartridges into boxmagazines directly fromcartons, the combination with a. pivotal loading-head having aloading-face, of cartridge-guides having their edges inclined to co-actwith the said head to rock the same on its pivot as it descends for"insuring the entrance of the successive cartridges of the column into 80the mouth of a box-magazine at the same angle.

6. In a device for loading box-magazines for firearms, the combinationwith a chambered upright having its front face flattened and slotted, ofa spring-actuated plunger located in the said upright, a cartridgeloading-head pivoted to the said plunger and traveling up and down inthe said slot, magazine-supporting means, cartridgegui-des carried bythe said upright and interposed between the said head and the saidmagazine-supporting means, and means for rocking the said head upon itspivot so as to cause the successive cartridges to enter the mouth of themagazine at the same inclination.

7. In a device for loading box-magazines for firearms, the combinationwith a chambered upright, of a base therefor, a lower box-magazinesupport upstanding from the said "base, a loop-like uppermagazine-support applied to the upright at a point directly above thesaid lower support, a spring-actuated plunger located in the chamber ofthe said upright, a loading-head pivotally connected with the upper endof the plunger, and cartridge-guides carried by the said upright andadapted to receive 110 the said head which descends between them and torock the same upon its pivot during its descent.

8. In a device for loading box-magazines for firearms from cartons, thecombination 115 with a pivotal loading-head having a load ing-face,provided with an operating-handle and carrying an operating-pin locatedsub stantially below the said handle, of cartridge-guides having theiredges inclined 120 for cooperation with the said pin for rocking thesaid head during its descent between the said guides, and means forpositioning and supporting a box-magazine below the said guides duringthe loading operation.

9. In a device for loading box-magazines for firearms, the combinationwith means for forcing a column of cartridges into the mouth of abox-magazine, of a loop-like magazine support cut away on one side, 130
